We’ve launched a new FB page.
“FMA Strategies & Tactics”
This page will focus on Filipino Martial Arts for contact fighters.
We’ll be pulling the drills, and danced apart yo find exactly where the practical applicationscan be found so you’ll know when and where to use them. This page will basically be an advertisement for our FMA Strategies & Tactics podcast we’re designing.
February 1st, 2026…earlier this month…my son Jonathan, Eric “Top Dog” Knaus, and I went to Austin Texas to interview 5 Escrimador fighters and coaches.
There’s a ton of information there to edit and sift through, but hopefully the show will be up and running in the next few weeks.
It’s a much larger task than I thought it’d be. We’re also testing out new equipment and how to put it all together, which places to host the show…Apple, Spotify, etc…and how to pay for all the places we want to go and people we want to talk to.
This page will be focused on fight tactics. How to close distance on a taller opponent, do you prefer a stick or knife, which grip do you prefer, offensive or counter offensive fighter, what footwork do you use when being charged by a heavy opponent? And much more.
I’ll end up posting some of our example question lists on the FMA S&T page so you can see what we’ll be covering. Obviously the lists will focus more on the person we’re interviewing, but you’ll get the idea.
So again, join us there/here on FB to see what we’ve been working on.
C/ya soon.
